Cystic fibrosis occurs as a result of inheriting a recessive allele for it from both parents. ... It states that different pairs of genes are passed to offspringindependently so that new combinations of genes
Cystic Fibrosis is a genetic disorder, 2 parents have a CF gene, if their offspring inherits that trait they will have Cystic Fibrosis.
Cystic Fibrosis, is a recessive disease (meaning that both parents must be carriers of the cystic fibrosis gene, for the offspring to have a chance of being born with it). A child has a 25% chance (1/4) of being born with Cystic Fibrosis.

No, cystic fibrosis is a genetic condition. Both parents carry the gene.
Both parents had at least one allele for cystic fibrosis.
Assuming that each parent is a carrier for cystic fibrosis (has the genotype Ff), the probability that their second child will develop cystic fibrosis is one fourth. The probability doesn't change with the number of children they have. For each pregnancy, the chance that the child will have cystic fibrosis (have the genotype ff) is exactly the same.
They are caused by the genes that we inherit from our parents. Genes govern how our body is run. Cystic fibrosis is caused by a recessive alle. This means that both parents must be carriers of the alle responsible for cystic fibrosis. The parents don't have to have the condition themselves; they can be just carriers of the one alle that makes up the condition.
No. Cystic fibrosis is an autosomal recessive disease. Each parent would have to be a carrier of a CF mutation and would be Cc.
Let's call the gene "C." Capital C means no cystic fibrosis; lower c means cystic fibrosis, since it is a recessive gene. CC is a person who does not have cystic fibrosis and also is not a carrier. Cc indicated a carrier. cc shows a person with cystic fibrosis. In order for a child to have cystic fibrosis, its parents must be: 1. cc and cc (both have cystic fibrosis, so every child will as well.) 2. Cc and Cc (both carriers; 25% chance of having a child with cystic fibrosis) 3. Cc and cc (one parent is a carrier and one has cystic fibrosis; there is a 50% chance that the children will have cystic fibrosis.)
If both parents are carriers on cystic fibrosis, just because two children may have the disease it doesn't mean that say,a further 3 children in future will be "normal". Inheriting genes is like a lottery. I can say though that because cystic fibrosis is recessive, every offspring born under carriers will always have a 75% chance of being phenotypically normal.
What is cystic fibrosis? Cystic fibrosis is a life threatening disease.
To have cystic fibrosis both parents have to be a carrier. Each parent passes on one of their genes to their children; they each have one healthy and one cystic fibrosis gene. The child with cystic fibrosis receives a cystic fibrosis gene from each parent. The other child has at least one healthy gene if she does not have cystic fibrosis, though she could be a carrier. hope it would help
